Dallas — A mixture of pain, fear and anger continues to permeate the city of Dallas three days after an Army veteran shot 12 police officers.

On Sunday, people began having conversations and talking about their fears and concerns in the wake of the shooting and discussing what they would like to see happen next.

At the southeast substation, officers have opened the doors to the community. People have been leaving balloons and flowers outside and many have been seen walking up to hug officers and share condolences.

"There's good cops and there's bad cops and there's good people and there's bad people and, unfortunately, some decisions might not have been the right decisions on either side but...what happened on Thursday is absolutely not the answer," Dallas resident Rich Guerra said.

Dallas police Sgt. David Burroughs said his entire department is grieving, but they understand that grief can't get in the way of their jobs.

"Despite the events of that night, we have to plan for the future and the future includes business as usual the next day and being up to 24, 36, 48 hours makes it extremely difficult to carry on business as normal," he said.

Burroughs said officers haven’t received any special orders in terms of changing standard operating procedures since the shooting.

“We have no special rules regarding how to treat people because our general rule is that we treat people the way we want to be treated and I think that’s the golden rule that our parents teach us,” he said.

As the mourning and grief continue, Burroughs is aware of the tough conversation that lies ahead and admits there are legitimate concerns coming from people who are protesting.

Dallas City Councilman Adam McGough said he believes the city will eventually get back to a sense of normalcy, but it will be a new normal.

McGough spent much of the last couple of days talking to people in the community about their fears, concerns and possible solutions.

"It's a diverse community. We come from every background; race, ethnic and socio economic and everybody is coming out here to support these officers and that's the kind of community we have here in Dallas," he said.
